L 1 nail hoflzonto shaft attention to the necessity of of the bracket 28and rests on a ide 427 having two slots and sliding on twoscrews 48, 49on the side of the bracket 28. The slide 47 has pivotally securedthereto a lever 50 which extends upward and connects with a short linkor level .;1 rigidly secured to the As previously stated, the shaft 29supports the mechanism operated by the button 37. ll hen the button isin its top or released position, as shown in Fig. l. the shutter isclosed and in tension and held in this condition by means of a catchoperated by the shaft 29. This catch consis'n' of av lever 52 mounted onthe shaft .29 and has a curved vertical extension which is pivotallyconnected to a lever ."i-l secured with its top to the top side end ofthe bracket 28 by means of a pivot This lever has an inward catch onwhich rests the horizontal portion of the shutter bracket 46, when thebutton 37 is released and in its high posit-ion. Upon pushing the buttondown the lever 50 moves downwardly and takes along the slide with thelingers 4:7 and the shaft 47 whereby the film is moved downwardly, butthe shutter remains closed because the horizontal portion of the bracketall, is held in its upper position by the catch oi the lever 54L. 'l heinner lever 52 oi this catch has on its lower portion below the shaft 29an inward extension with stop pin and spring 52 at its end and when thefilm portion with a new picture has reached the shutter opening, thenthe lever 51 has reached the pin and forces the catch mechanism inwardlywhereby the lever 5" is moved away from the horizontal arm of theshutter bracket 46, by means of the curved lever 53. thus relcasingtheshutter which now drawn. down by the shutter spring 4-5 until its lowerend strikes the stop plate Now an image is thrown on toe screen for aslong a time as desired. To show a new picture the release lever 38 isoperated whereupon the button mechanism is released, the shutter closedand tensioncd and the button 37 returned in its upper position. It nowthe button is pressed down again the described cycle of operations isautomatically repealed and a new picture shown. To insure the safemovement of the lever 38 a. guide strip 38 is provided on the top of thecamera casing, as shown in Fig. l.

As hereinbefore stated. the film contains pictures with the objectsthereon in the normal upright position and pictures with long objectsthereon in the horizontal position. "In order to throw the images of thepictures with the objects in the horizontal position on the screen inthe normal up right position, the projecting apparatus is turned 90 byvirtue of the mechanism previously described. To call the operatorsturning the projecting apparatus, an indicitor is provided which isautomatically operated by the 'lilm when the latter is automaticallymoved. This indicator is actuated always before such picture reaches theshutter opening. Various indicators may be used. On the drawing oneindicator is illustrated consisting of an alarm arrangement.

Vhen the positive film is finished, the usual openings to near the edgesare provided and incisions 57 are made on the side where the indicatoris located. Such incision actuates a lever 58 mounted on a pivot 59.This lever has at the bottom an inward portion 60 with end pin (31.along which the film moves with the adjoining edge portion. However,when an incision 57 passes the pin (31 said pin enters the incision andcauses the head or clapper 62 to perform a movement toward the leftstriking an electric alarm indicated by a contact 62, see Fig. 7.

A spring 63 may be provided on the lever .to insure the reliable workingof the indicator. The head or clapper 62 may es tahlish an electriccontact, which lights'a miniature electric lamp for a. moment or ringsan electric hell, or exhibits a sign on the outside of the apparatus.For square pictures with the objects thereon in the normal uprightposition. no indicator is necessary. but the novel bracket shutterrelease which contains but one shutter is required. he indicator solelyserves for calling the attention of the operator to the necessity ofturning the projecting apparatus before a picture with the objectsthereon in horizontal position reaches the shutter openinq". Theapparatus casin in course, is fireprooI.

ll'hen. um source o'l? light or lamp is in its normal position close tothe camera, no danger oi igniting the film exists because the film isnot located in the plane of the l ocal point. Assuming thatcircumstances arise which require that the lamp be moved out or takenaway. then at a certain moment the focal point of the lenses 6% would beon the film and the film would explode.

To prevent this the rear wall of the camera casino" has a shutter 65which is automatically operated by the moving out of the lamp. Theshutter is provided with a pin on which meets on the top or" the lenscasing (37 during the operation of the projecting amYaratus. if the lampis withdrawn and haspassed the pin 66, the shutter slides down, bygravity and closes the openin 'lo render this operation sccure. a springis altarl'icd lo the lower end of the shut- ")5 which draws the shutterdownwarc n the pin (W) has been released. This up is not absolutelynecessary when the riveting ;u paratus is in the normal upi ht position.because u shuttcr will slide llowcver. when the projet-ting apparatusdown by gravity.
